摘要： A manufacturing method for a bent product which can guarantee a high working accuracy and which can provide a large bending angle without damage to the surface condition of a metal material even when a widely varying bent shape is desired or when it is necessary to perform bending of a high strength metal material.A bent product having a three-dimensionally bent portion intermittently or continuously in the lengthwise direction is manufactured by supporting a steel pipe 1 at a first position A while feeding it in the lengthwise direction, locally heating the steel pipe 1 being fed at a second position B, cooling the heated portion of the steel pipe 1 at a third position C, and varying the position of a gripping means 15, which grips the steel pipe 1 in a region D downstream of the third position C, in a three-dimensional direction including the feed direction of the steel pipe 1 in a workspace including a space on the upstream side of the third position C in the feed direction of the steel pipe 1 to impart a bending moment to the heated portion of the is steel pipe 1.

摘要： Using as a vehicle body reinforcing member a bent tube with mixed bends of inward and outward projection according to the present invention makes it possible, during a vehicle body collision, to absorb more energy than and exhibit better impact resistance than a vehicle body reinforcing member that uses one of a known straight tube and a curved tube of radius R entirely. Thus the dimensions (outside diameter, wall thickness) of the steel tube that is used as the vehicle body reinforcing member can be reduced, and the tube shape can be modified, while impact resistance is maintained. Modifying the shape in this manner makes it possible to provide the ever higher required level of vehicle body impact resistance at the same time that it reduces the weight of the vehicle body and lowers the cost. The present invention can therefore be widely used as an occupant protection technology.
